Recently, policies encouraging the production of fuel ethanol have resulted in an enormous increase in the production of “new generation” distiller’s dried grains with solubles (NG-DDGS). “New generation” distiller’s dried grains with solubles refers to DDGS from modern non-beverage fuel ethanol plants, which exclusively use corn in the fermentation process. The present studies were conducted to evaluate the use of NG-DDGS in poultry diets and to determine the lysine and phosphorus bioavailability of NG-DDGS. Based on the data, 6% NG-DDGS can safely be used in starter broiler diets, and can be increased to a 12% level during the grower and finisher periods. Six to 8% NG-DDGS can be fed in layer diets during peak production, and once body weight and feed intake have stabilized the NG-DDGS level can be increased to 10 or 12%. The lysine and phosphorus availability of NG- DDGS was estimated to be 80% and 61%, respectively.
